Hi, I bought an oximeter because I have PAF and it is useful as a quick check of hr etc. I also have asthma and my resting SATS are 97/98 which I believe are not relevent to my asthma but more to my heart function? My question is because my husband, who is quite susceptible to chest infections has not been himself lately, had a cold, tired, breathless, a bit confused and grumpy. I noticed him sounding breathless when he came upstairs to bed so I checked his SATS which were 93. This morning while resting it was 93/95. I had thought he was breathless because he had a blocked nose but I guess not? I think he is worrying because he thinks he is developing dementia but I have noticed these symptoms come and go so I wonder if he has a lung problem? He had an xray a couple of years ago because of a chronic cough.
Hope you can help, thanks.
